Wednesday, October 12. 2005From RAID-1 to RAID-5 on the fly![]() It was more complicated than I thought, but it finally was and therefore is possible to move a system from (Software-)RAID-1 using 2 disks to (Software-)RAID-5 using 3 disks without the help of an additional disk during transfer. Some things I had to keep in mind:
After that I could do the usual mounting, rsync’ing and dual booting, praying that no disk fails right in that “degraded array phase”. As everything seemed to work, I repartitioned hda and raidhotadd’ed it to the running system. The sync for the 147GB array took about 90 minutes. |
